23:33 <re_irc> <Jeremy Fitzhardinge> Hey all - What's the best way to use an i2c controller via embedded-hal-async for multiple devices? It seems that a lot of the drivers just want to take ownership of the whole i2c controller. Is there some meta-i2c controller to allow sharing?

23:34 <re_irc> <newam> This is probably what you're looking for: https://docs.rs/shared-bus/latest/shared_bus/

23:34 <re_irc> It gets a lot better with the embedded-hal 1.0.0 traits (still in alpha)

23:35 <re_irc> <Jeremy Fitzhardinge> Ah, thanks for the pointer. I am using embedded-hal 1.0 alpha - should you use shared_bus with that, or does it have its own mechanism for this?

23:37 <re_irc> <newam> You can use shared bus with EH 1.0 alpha, but it's also easy to make your implementation if you have unique requirements, that's really the advantage with 1.0

23:39 <re_irc> <Jeremy Fitzhardinge> does shared-bus support async?

23:40 <re_irc> <newam> I think it works with async, but I'm not 100% on that. Async is even more alpha than EH 1.0 alpha :D

23:40 <re_irc> Take a look at embassy (https://github.com/embassy-rs/embassy) (also #embassy-rs:matrix.org (https://matrix.to/#/#embassy-rs:matrix.org) ), I'm sure they have something there.

23:46 <re_irc> <Jeremy Fitzhardinge> Ah good point, I should catch up with what's been going on in embassy-land

23:54 <re_irc> <Jeremy Fitzhardinge> looks like it has an async shared bus https://docs.embassy.dev/embassy-embedded-hal/git/default/shared_bus/asynch/index.html
